Abstract

Flame resistant compositions based on nylon-6 (PA 6) or nylon-6,6 (PA 66) may include melamine cyanurate, titanium dioxide, glass fibers, and non-fibrous and non-foamed ground glass having a specific particle size distribution, geometry and optionally sizing. Methods for producing the composition are also provided, as well as use of the compositions for production of products for the electrical industry, preferably electrical components such as residual current circuit breakers and other circuit breakers.
